Those currently proposing forced vaccination laws point to a U.S. Supreme Court decision from 1905: Jacobson v. Massachusetts. In fact, the Supreme Court has not heard a compulsory vaccine case since the 1920s.
In the article presented here, Attorney Emord looks at the history of compulsory vaccination, and shows how it was Oliver Wendell Holmes, Jr. who stripped away Fourteenth Amendment rights in regards to compulsory vaccination, the very same judge who ruled in favor of forced sterilization which was supported by the "science" of that day, eugenics. Eugenics is the same "science" used by the Nazis in Germany to endorse eliminating "feeble-minded" people in favor of a "master race."
